Each version of Excelsior JET goes through three lifecycle stages:
- Current Offering
- Begins on the date of the first commercial shipment of the given version, and lasts until the next version becomes the Current Offering. Only the Current Offering is, well, offered for evaluation and purchase.
- End of Sales
- Entered when a newer version becomes generally available. All versions that are in the End of Sales stage are fully supported, but are unavailable for purchase and may not get public updates anymore until very late in this stage.
- End of Life
- Two years after the first commercial shipment*, a version goes into the End of Life stage. Versions that are past their End of Life date are not supported, but public updates remain available for download indefinitely.
* You can find the shipment dates for all Excelsior JET versions in the changelog.
If we have released a newer version during your 90-days evaluation period and you do not want to switch over immediately, let us know at the time of purchase, and we will provide you with a copy of the version that you've evaluated.
Java Version Updates
As Excelsior JET includes licensed code of the Oracle's implementation of the Java SE standard library, its update schedule is synced with the Oracle Java update schedule.
Public Excelsior JET Updates
A Maintenance Pack is a cumulative update that contains bug fixes and minor improvements, and may also include support for a recent Oracle's Java Technology update. Maintenance Packs are available at no additional cost to all users of the respective Excelsior JET versions at all times.
We guarantee to issue a Maintenance Pack for the Current Offering version of Excelsior JET every three months, in sync with the Oracle Java update schedule, plus one more Maintenance Pack for each version shortly before it reaches its End Of Life date.
In addition, once a major Java version approaches its End of Public Updates date, we issue a Maintenance Pack for the last version of Excelsior JET based on that version of Java. That Maintenance Pack includes support for the last public update of the said major Java version, which in the current scheme of things would be a PSU.
For instance, 10.5 is the last version of Excelsior JET that supports Java SE 7. Therefore, Excelsior JET 10.5 MP2 includes support for Java SE 7 Update 80, which is the last publicly available Java SE 7 PSU release.
Frequently Asked Questions
- What are the wait times?
Normally, we issue a Maintenance Pack for the current version of Excelsior JET with support for the latest Oracle Java CPU release in two-three weeks after the latter becomes available from Oracle.
However, at the moment it is impractical for us to work on supporting a Java update in the current version of Excelsior JET when the the next version is already late in its pre-release cycle, as doing so would effectivley double the load on our build/test infrastructure and staff.
Therefore, we guarantee to either update the current version of Excelsior JET to support the latest Oracle Java CPU release in two-three weeks after the latter becomes available from Oracle, or release a new version supporting that CPU release out-of-the-box in four to six weeks.
- What about the Limited Updates?
The CPU immediately following the given Limited Update will have included all the improvements and new features introduced in the latter, plus fixes for issues in that new code that may have slipped through Oracle's QA. Therefore waiting for the next CPU release is a safer play. But if there is something in that Limited Update that you or your customers absolutely need right now rather than in a couple of months, we have a commercial service offering for you.
Commercial Maintenance Services
Java Update Support
There are scenarios in which you may need your copy of Excelsior JET to support a Java update other than the latest CPU:
- Your application is impacted by one of the additional bugs fixed in the latest PSU
- Your application is impacted by a bug introduced in the latest CPU
- You want to take immediate advantage of an improvement introduced in the latest Limited Update
- You are stuck with the previous major version of Java (and hence with a legacy version of Excelsior JET)
- and so on.
In most situations of this kind, you can order the creation of a Maintenance Pack with support for a specific Java update. For information about pricing and delivery time, please email us which Java SE Update you need us to support in which version of Excelsior JET.
